get data from dataset

I have a dataset, which is filled by a query of 3 tables. Now I want to get a column data from the dataset, how? thanks.

This has some basics on filling a dataset and getting data from it:

Although I am a bit confused - it would seem that the harder thing to do would be to actually get the data into the dataset, no get the data out of the dataset. Do I understand you correctly?

my dataset is filled by a sql like this:

VB Code:

sql = "Select tblModule.* ,tblTemplateModule.TemplateIndex From tblModule,tblTemplateModule "
            sql = sql + "Where tblModule.ModuleNumber = tblTemplateModule.ModuleNumber and tblTemplateModule.TemplateIndex = " + Str(templateRow("TemplateIndex"))

I get one record from the query and want to display tbllModule.Name to a treeview control. But I just can not get that column data.

VB Code:

daTemplateModule.SelectCommand = New OdbcCommand(sql)
            daTemplateModule.SelectCommand.Connection = New OdbcConnection(conString)
            daTemplateModule.SelectCommand.Connection.Open()
            Try
                dsTemplateModule.Clear()
                moduleCount = daTemplateModule.Fill(dsTemplateModule)
                ' daModule.SelectCommand.ExecuteNonQuery()
            Catch MyOdbcException As OdbcException
                Console.WriteLine(MyOdbcException.ToString)
 
            End Try
 
            For i = 0 To moduleCount - 1
                '    For Each moduleRow In dsTemplateModule.Tables(0).Rows
                Dim moduleNode As TreeNode = New TreeNode()
                moduleNode.ForeColor = Color.DarkGreen
                moduleNode.ImageIndex = 1
                moduleNode.Text = dsTemplateModule.Tables(1).Columns("Name").ToString
                templateNode.Nodes.Add(moduleNode)
        next i
